A port of March22 Interactive Novel engine to Lua for use with the LÖVE framework.

User guide

Works with LÖVE out of the box. Clone the repo and drag the folder onto the love2D executable.

If you are porting - Process the scripts with RPYtoLua (uses so doesn't compile on Linux). Doesn't like indentation.

If you are developing - Write your scripts in the March22 format and refer to documentation. Compile using M22toLua.

If you want Visual Novel or PS Vita support, clone the appropriate branch.

Changelog

v0.6.7

• Fixed bug/typo with active music in savegame.
• Long-text support from RPYtoLua.

v0.6.6

• Added active music to savegame.
• Multiple script support:
  • Checks if iscene exists in current script; if not, loads necessary script then jumps to it.
  • Seems to work on PC, don't know about PSVita yet.
  • Needs more assets to really test, though.
• Updated RPYtoLua:
  • Outputs .lua files instead of .rpy.lua files (because it breaks the crap out of love2d).
  • Working on an automated installer script so as to not violate Katawa Shoujo's license (see installer folder).

v0.6.5

• Wrapper for LÖVE:
  • Means can dev on PC/Mac/Linux without a PSVita.
  • Still needs PSVita for debugging console-specific stuff though.
• Added explicit garbage collection in hopes it fixes running out of RAM.
• Fixed savegames only working when saved during narrative.
• Todo:
  • Add active music to savegame.
  • Test multiple script deployment.
  • Music file streaming from storage as opposed to preloading.
  • Update RPYtoLua to remove .rpy from end of script name so it doesn't end up as "file.rpy.lua".
    • Breaks love2d for some reason.

v0.6.3

• Decision trees:
  • Handled by imachine.lua.
  • Scripts call "MakeDecision()" with the appropriate parameters.
  • This function hijacks the framebuffer to draw the decisions onscreen.
• Saving/loading:
  • Works well enough for one load, but fails at line 172 (one of the music tracks) for the script.
  • Probably a RAM issue; some sounds not getting freed properly?
  • Should try and stream from storage instead of preloading..
• New RPYtoLua specifically for compiling imachine.lua.

v0.5.0

• Fixed every bug listed on the first binary release:
  • Refer to that buglist; it pretty much is the changelog for this version.

v0.4.0

• Added fadein/out for drawcharacter and clearcharacter.
• Added typewriter effect.
  • Breaks unicode characters.
• Improved stability of RPYtoLua when it comes to animations.

v0.3.5

• Added per-script loading of character sprites to RPYtoLua.
  • And subsequent drawing/clearing to March22-Lua.
  • Garbage cleanup was already in place? Need to verify.
• Improved new-script loading to be more stable.
• Probably some other stuff; I forget.

v0.3.0

• Added ability to load new scripts.
• Improved RPYtoLua stability.
• Added garbage cleanup to loading new script (unloads graphics/sounds from [V]RAM).
• Added function to add characters to screen.
  • Uses "twoleft", "offscreenleft" and "center" for positioning.
  • This needs to be added to RPYtoLua though.
  • Also needs animation.

v0.2.0

• Improved script loading.
• Added a loading bar function.
• RPYtoLua.
  • C++ program that converts RPY script to March22-Lua-compliant Lua script..
  • Currently only converts dialogue and sound/background changes, with no transition.
  • Requires setup to charnames and charnames_fixed, similar to RPY-eBook.
• Other stuff I probably forgot.

v0.1.0

• Initial commit.
